Submarine Fan of Steep Slope Belt and Its Prospect for Petroleum Exploration in Shida Sag, Jiuxi Depression

Abstract

Abstract: The Shida sag in Jiuxi depression is a Mesozoic-Cenozoic halfgraben-like basin with faulting in east and overlap in west. In the steep slope belt of Shida Sag, there deposited some submarine fan sandbodies. The sandbodies often sinked into the hemi/deep lacustrine dark mudstone and featured both source and reservoir in them. So, the hydrocarbon accumulation conditions are superior with great potentials for exploration.

Key words: submarine fan, sedimentary feature, lithologic reservoir, Shida sag, Jiuxi depression
